Connect to ADP Data in Squirrel SQL Client



Connect to ADP data and execute queries in the Squirrel SQL Client.

The CData JDBC Driver for ADP enables you to execute queries to ADP data in tools like Squirrel SQL Client. In this article, you will create a JDBC data source for ADP data and execute queries.

Add the JDBC Driver for ADP

Follow the steps below to add the driver JAR.

  1. In Squirrel SQL, click Windows -> View Drivers.
  2. Click the plus icon to open the Add Driver wizard.
  3. In the Name box, enter a user-friendly name for the driver; for example, CData JDBC Driver for ADP.
  4. In the Example URL box, enter jdbc:adp:
  5. In the Extra Class Path tab, click Add.
  6. In the file explorer dialog that opens, select the JAR file for the driver, located in the lib subfolder of the installation directory.
  7. Click List Drivers to populate the Class Name menu with the class name for the driver, cdata.jdbc.adp.ADPDriver.

Define Connection Properties

Follow the steps below to save connection properties in the driver alias.

  1. Click Windows -> View Aliases.
  2. In the pane that lists the aliases, click the plus icon.
  3. In the Add Alias wizard that opens, the following fields are required for the JDBC driver:

    • Name: Enter a name for the alias; for example, CData ADP Source.
    • Driver: Select the CData JDBC Driver for ADP.
    • URL: Enter jdbc:adp:
  4. If you want to define any additional properties, click Properties.
  5. In the Driver properties tab of the dialog that appears, select the Use driver properties checkbox.
  6. In the Specify column, select the checkboxes for the required connection properties.

    Connect to ADP by specifying the following properties:

    • SSLClientCert: Set this to the certificate provided during registration.
    • SSLClientCertPassword: Set this to the password of the certificate.
    • UseUAT: The connector makes requests to the production environment by default. If using a developer account, set UseUAT = true.
    • RowScanDepth: The maximum number of rows to scan for the custom fields columns available in the table. The default value will be set to 100. Setting a high value may decrease performance.

    The connector uses OAuth to authenticate with ADP. OAuth requires the authenticating user to interact with ADP using the browser. For more information, refer to the OAuth section in the Help documentation.

    Below is a typical connection string:

    jdbc:adp:OAuthClientId=YourClientId;OAuthClientSecret=YourClientSecret;SSLClientCert='c:\cert.pfx';SSLClientCertPassword='admin@123'InitiateOAuth=GETANDREFRESH
  7. In the dialog that appears after you click OK, click connect to test the connection.

Discover Schemas and Query ADP Data

After the metadata has loaded, a new tab for the ADP data source is displayed. On the Objects subtab, you can discover schema information, such as the available tables and views.

To view table data, select the table on the Objects tab. The table data is then loaded in a grid on the Content tab.

To execute an SQL query, enter the query on the SQL tab and then click Run SQL (the runner icon). For example:

SELECT AssociateOID, WorkerID FROM Workers WHERE AssociateOID = 'G3349PZGBADQY8H8'
